\begin{frame}{Final Remarks - EEP vs. UEP}
Implementing UEP can be considered when:
\begin{itemize}
\item{Data differs in importance}
\item{Part of the data is expendable}
\item{Heterogenous, unknown or time-varying channel conditions}
\end{itemize}
$ $\\
For EW, the design considerations then include:
\begin{itemize}
\item{The degree of importance and protection}
\item{The amount of overhead}
\item{The structure of the EW scheme}

%\item{$\Gamma_{1,\hdots,i}$, $K_{1,\hdots,i}$}
%\item{Always a degree of freedom}
\end{itemize}
